ANZ200 104 Pm Edt Fri Jun 21 2024

Synopsis for massachusetts and rhode island coastal waters - A weak backdoor front will move east to west into new england Friday, then remain nearly stationary Saturday. This will serve as a focus for showers and Thunderstorms. Meanwhile, winds will be light and variable along with areas of fog at night. The boundary lifts north as a warm front Sunday. This will be accompanied by increasing southwest winds, along with a risk of showers and Thunderstorms in the afternoon and evening. Low pressure moves across new england Monday, accompanied by showers and Thunderstorms. Improving conditions likely Tuesday, as the low exits into the maritimes. A cold front may then enter new england Wed or Thu.

Area Forecast Discussion National Weather Service Boston/Norton MA 938 AM EDT Fri Jun 21 2024

SYNOPSIS
A backdoor cold front moves in from northeast to southwest Friday...bringing another round of showers and thunderstorms but also breaking the dangerous heat and humidity for much of the region. Thunderstorms will be focused across western-central Massachusetts and Connecticut...where some of the storms may become severe and also result in a localized flash flooding. Warm and muggy this weekend with rain and thunderstorm chances both Saturday and Sunday. A cold front sweeps across the region Monday with additional showers and storms, then a drying trend and less humid Tue before heat and humidity return midweek.

NEAR TERM /UNTIL 6 PM THIS EVENING/

935 AM Update...

* Another round of showers & t-storms this afternoon/early eve * Focus will be across interior MA, CT, western RI * Severe Weather/Flash Flood Risk...interior MA/CT/Western RI

Many locations have already seen temperatures reach into the 80s
However
a backdoor cold front will be pushing westward towards the CT River Valley by early afternoon. As a result...temps along the immediate eastern MA coast will drop into the 70s but remain in the 80s not too far inland from the coast
In fact
the flow behind the front is relatively weak so expect highs to still reach the lower to middle 90s in the lower CT River Valley where Heat Advisories continue through the afternoon.

The biggest concern will be for another round of showers & t-storms as shortwave energy coupled with diurnal instability combined with the backdoor cold front. Activity should develop by early-mid afternoon and while all areas are subject to be impacted...the bulk of the storms today will focus across interior MA/CT and western RI. This is where MLCapes may reach between 1500 and 2000 J/KG and also have some forcing along the backdoor cold front. While instability is not as high as yesterday...0-6 KM shear will be on the order of 20 to 30 knots somewhat better and low level lapse rates will be steep. This will support the risk for a few severe t-storms with the focus for them across interior MA/CT and western RI. The various Machine learning guidance also highlights this region.

In addition...these backdoor cold fronts always need to be watched for a localized flash threat. Pwats of 2+ inches will support torrential rainfall with any storms and there is the potential for some training along the backdoor front. The CSU Machine learning probs do show the potential for excessive rainfall across interior MA/CT and western RI
In fact
the HRRR indicates some low probs for the 6 hour QPF to exceed a 100 year rainfall event. That certainly does not mean that will happen...but is at least a signal for potential localized flash flooding. This is particularly true if the activity would train over a particularly vulnerable urban center.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/
220 AM update...

Much like last night, instability will drop off quickly with sunset as an elevated mixed layer develops above the cap. Thus, don't expect the storm/low severe threat to persist much past 0

Will need to watch for stratus/fog formation tonight given onshore flow and a lot of residual moisture post storms. Overnight lows will again remain quite mild across the interior, but lower dewpoints in the low 60s across eastern MA will provide somewhat of a reprieve there.

It's almost a "copy paste" type forecast for Saturday with the quasistationary frontal boundary still draped over our region.
Onshore flow should advect "cooler", well in this case "seasonable" air well inland, with high temperatures ranging from the low 70s in northeastern MA to the upper 80s to perhaps 90F across central Connecticut.

Will need to monitor another wave of convection Saturday afternoon, though hi-resolution guidance remains widely varied in the coverage and intensity of storms, with the NAM3k showing a more conservative solution of isolated cells and other guidance like the FV3 diagnosing an early evening convective line. The strongest cells are again expected along the frontal boundary, dissipating quickly after 01- 02Z tomorrow evening as the elevated mixed layer redevelops.

Hazards on Saturday are generally consistent with what we will see on Friday given a near identical synoptic setup. Damaging wind and urban/localized flash flooding are again possible.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
220 AM update...

Highlights:

* Heat and humidity likely return Sunday with PM T-storms possible, especially CT into western-central MA

* Another round of T-storms possible Mon, followed by a drying trend Tue and less humid, before heat and humidity return mid week

Saturday night...

Any early evening convection along the stalled boundary should diminish with sunset or shortly thereafter, as short wave ridging begins to advect in from the west. This will also lift the stalled boundary northward as a warm front. Thus, warm sector airmass will yield a mild night along with patchy fog given increasing dew pts.
Low temps will only fall into the 60s.

Sunday...

Strong WAA with ensembles advecting +20C to +21C 850 mb air across SNE! Deterministic guidance has +25C air at 925 mb streaming into the region from SW to NE, with hottest air over CT. However, guidance is not as hot given such warm temps aloft. Much of the guidance offering highs 85-90 Sunday afternoon, with hottest numbers across CT. Models do have a lot of cloud cover around Sunday and some of the guidance suggest the stalled boundary from Saturday doesn't completely lift north and exit the region, supporting the idea of cooler temps especially across northeast MA. For now, stuck close to guidance but if true warm sector airmass overspreads the region, highs could soar well into the 90s and combined with dew pts of 70-75, heat indices of 95 to 104 would be possible. Hence, dangerous heat and humidity. Scattered thunderstorms are possible in the afternoon/early evening across CT and western-central MA, pending the amplitude of a lead short wave which may induce a prefrontal trough to focus the convection. Greatest risk for PM storms will be across CT into western-central MA.

Monday...

Another round of thunderstorms expected Monday, as potent short wave/closed mid level low and attending cold front approach the region. Not as hot as Sunday, but remaining very warm and humid, with highs 80-85 and dew pts in the upper 60s to lower 70s.

Tuesday...

A brief break from the heat, humidity and drier weather, as closed low exits and moves east of our longitude, with drier WNW flow. Dew pts fall into the low and mid 60s, possibly some upper 50s western MA. Pleasantly warm with highs in the low to mid 80s, but noticeably lower humidity.

Wednesday/Thursday...upper air pattern is progressive so return flow develops mid week, with warm and more humid weather advecting into SNE. Highs 85-90 Wed, then likely not as hot Thu given increasing risk for showers/thunderstorms with highs in the upper 70s and lower 80s.

AVIATION /13Z FRIDAY THROUGH TUESDAY/
Forecast Confidence Levels:

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

12z TAF Update...no change from previous TAF thinking. Scattered thunderstorms from 16z-22z approximately today, with coverage most numerous across CT/RI and into western-central MA. SW winds become ENE across eastern MA, as backdoor front comes onshore.
Earlier discussion below.

=====================================================================

Friday...Moderate Confidence.

More showers and thunderstorms this afternoon with more north to south coverage compared to Thursday when storms stayed north of the MA Turnpike. Anticipating VFR conditions, with the exception of patchy IFR due to fog, through 15Z after which time storms will bubble up. VFR/high end MVFR with cigs around 3500ft outside of storms. MVFR to IFR in storms with potentially torrential downpours and vsby reductions. Will be difficult to pinpoint exact storm location but terminals at greatest risk are BAF, BDL, ORH, PVD. Winds variable today, from the ENE from ORH, east, and from the NW/W across the CT River Valley as cold front pushes west towards interior southern New England.

Friday night...Moderate Confidence.

Bulk of storms wind down by 00Z tonight, but residual moisture and onshore ENE flow will allow pockets of fog to develop.
Generally MVFR to IFR due to cigs.

Saturday... moderate confidence.

Another afternoon of scattered thunderstorms, though confidence on intensity and aerial coverage is low at this time. Could impact all terminals, or none at all with the best chance for tstorms coming after 17Z. Conditions improve from IFR/MVFR to VFR with perhaps the exception of east coastal MA where MVFR will persist. Locally lower flight categories likely again in storms.

KBOS TAF... Moderate confidence.

Expect thunderstorm activity to stay inland of Boston this afternoon, but can't rule out a stray storm. Generally VFR this morning becoming MVFR/IFR overnight due to low stratus/fog.
Winds quickly shift to the ENE this morning and will persist.

KBDL TAF...Moderate Confidence in TAF.

Another round of thunderstorms this afternoon with the best chance to impact BDL between 17-22Z. Storms wane quickly after sunset. VFR outside of storms, MVFR in storms, MVFR to IFR developing tonight due to fog. Winds from the West for much of the period but depending on the position of the back door cold front, could go N or ENE late in the period.

Outlook /Saturday Night through Tuesday/...

Saturday Night through Sunday: Mainly VFR, with local MVFR possible. Breezy. Chance SHRA, isolated TSRA.

Sunday Night through Monday: Mainly MVFR, with areas VFR possible. Breezy. SHRA likely, isolated TSRA.

Monday Night: VFR. Breezy. Chance SHRA, isolated TSRA.

Tuesday: VFR.

MARINE
Forecaster Confidence Levels:

Low - less than 30 percent.
Medium - 30 to 60 percent.
High - greater than 60 percent.

220 AM update...

Through Saturday...High Confidence.

Back door cold front will move across the northeastern waters on Friday morning but likely stalls somewhere across the southern waters, which will lead to converging winds; northeast vs westerly.

Afternoon showers and thunderstorms across the mainland may impact the waters very late both today and Saturday, but confidence is low as storms are expected to lose their strength after sunset. Winds and seas should stay below SCA criteria.

Fog and stratus development likely tonight and will linger into the day on Saturday. Reduced vsbys should be expected.

Outlook /Saturday Night through Tuesday/...

Saturday Night: Winds less than 25 kt. Areas of seas approaching 5 ft. Chance of rain showers, isolated thunderstorms.

Sunday: Moderate risk for Small Craft Advisory winds with gusts up to 30 kt. Local rough seas. Chance of rain showers, isolated thunderstorms.

Sunday Night: Moderate risk for Small Craft Advisory winds with gusts up to 30 kt. Areas of rough seas. Rain showers likely, isolated thunderstorms.

Monday: Winds less than 25 kt. Local rough seas. Rain showers likely, isolated thunderstorms.

Monday Night: Winds less than 25 kt. Local rough seas. Chance of rain showers, isolated thunderstorms.

Tuesday: Winds less than 25 kt. Areas of seas approaching 5 ft.
